ELECTRIC CONDUCTOR.

SPECIFICATION forming part of Letters Patent No. 399,826, dated March19, 1889. Application filed September 10, 1888. Serial No. 284,971. (Nomodel.

To all whom it may concern:

Be it known that I, ALFRED A. BROOKS, of Cambridge, in the county ofMiddlesex and State of Massachusetts, a citizen of the United States,have invented a new and useful Improvement in Electric Conductors, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming apart of this specification, in explaining its nature.

It is very desirable that the class of electric conductors which requireto be insulated or covered be protected with a jacket that shall betightly applied to the conductor, shall en tirely cover it with asufficient body of material to afford protection, and shall not be easily abraded and shall not unravel; and my invention relates to ajacketed electric con ductor the jacket of. which is provided with theseproperties by being made of .fillingthreads which are parallel with theconductor and two or more uniting-threads which are woven in and outamong the fillingthreads an d caused to be wound about the conductor.

In the drawings, Figure l is a view of the jacketed conductor having thefeatures of my invention. Fig. 2 is an enlargedviewthereof. Fig. is aview in horizontal section upon the line on L1; of Fig. 2. Fig. '-l is aview in horizontal section illustrating the jacket as having an exteriorcovering of water-proof material.

Referring to the drawings, a represents the conductor; b, the warpthreads or yarns; c c, the uniting woof threads or yarns, which aretightly wound around and about the conductor and interwoven with thelongitudinal threads or yarns Z) in parallel courses or lines, thethread 0 passing over the longitudinal threads I), while the thread 0passes under the same threads upon one complete circuit of the jacket.

I am aware that electric conductors have been covered with a wovenjacket havin g longitudinal threads or yarns and one connectingwoof-thread; but such jackets are quite easily worn by abrasion, and, ifthe woofthread is severed, very easily unravels; but with myconstruction the severing of one or both the woof-threads will notpermit or enable the jacket to be unraveled more than a course or two,the interweaving and interlocking of the two'strands e c wit-h thelongil tudinal strands, as above specified, preventing the raveling ofeither.

i There may be interposed between the conductor and the jacket a film orlayer of insulating material, (7, as represented in Fig. 3, and thejacket may be covered by an exterior water-proof coating, e. (See Fig.l.)

Havin thus fully described my invention, I claim and desire to secure byLetters Patent of the United States 1. An electric conductor consistingof a wire covered with a single-ply jacket composed of a single set oflongitudinal yarns or warps, Z), and two uniting woof or weft threads oryarns, c c, which are both tightly wound around the said wire andinterwoven with all of the said warps in parallel course or lines, saidweftthreads being alternated with the said warpthreads, so that in thesame course the thread (3 is beneath or inside of a warp-thread when athread, a, is above or outside of the same warp-thread, and vice versa,substantially as set forth.

2. An electric conductor consisting of a wire having an insulatii'iglayer or coating, ('7, and a single-ply tightly-woven jacket or coveringcomposed of a single set'of longitudinal yarns or warps, 7), and two ormore wefts interwoven with all the said warps and extending around theconductor in parallel course and passing alternately over and under thesaid warps, substantially as set forth.

An electric conductor consisting of awire having a tightly-wovensingle-ply j aeket composed of a single set of longitudinal warps, o,and two or more wefts, each of which is inter woven with all of the saidwarps and passing alternately over and under the same, said jackethaving a water-proof coating, substantially as set forth.

at. An electric conductorconsisting of a wire having an insulating layeror coating, (7, and a single-ply tightly-woven jacket composed of asingle set of warp-threads and two or more weft-threads, each of whichis interwoven with all of the said warp-threads, and said jacket havinga water-proof coating, 0, substantially as set forth.
